Document Type and Number:
WIPO Patent Application WO/2019/111826
Kind Code:
A1
Abstract:
Provided are: an antibacterial display body capable of making images with different appearances visible according to viewing conditions and enhancing the wavelength selectivity of an image produced from reflected light or transmitted light; a device provided with the display body; and a display body manufacturing method. This display body is provided with a periodic structure that is a dielectric comprising a support part, which has a reference surface, and a plurality of periodic elements that are arranged on the reference surface in a two-dimensional lattice shape having a sub-wavelength period, said periodic elements being projections that protrude from the reference surface or recesses that are sunken in relation to the reference surface. Additionally, the display body comprises a metal layer that has a shape conforming to the surface shape of the periodic structure and is positioned on the surface of the periodic structure, said surface including the surfaces of the periodic elements and a region of the reference surface surrounding the periodic elements, wherein the length of the gaps between the plurality of periodic elements along a first direction in which the periodic elements are arranged in the two-dimensional lattice shape differs from the length of the gaps between the plurality of periodic elements along a second direction intersecting the first direction.
